I just switched to AT&T prepaid $300 a year plan with 16G of data a month and one month carryover. That's $25 a month. I was a little confused about payment, I thought I needed to pay $300 up front which I did, but then they said I had to pay at least $25 a month. I got that straightened out. Make sure you get a PIN # from your carrier now to port your phone before you switch, it makes it easier. I think taxes made the total $321.40.
